The world of Fashionable Eyeglasses
From Tom Hanks to David Beckham or Julia Roberts all the major celebrities/film stars have been wearing eyeglasses. Whereas some branded eye wears have made great impact on the identity of these celebrities, some celebrities have gave impetus to the demand of eyeglasses of particular make; thus, the celebrity or the eyeglasses are complementary to each other. Today, fashionable eyeglasses also come with added features which provide effective protection against dangerous UV rays emitted by the Sun.
Some fashionable eyeglasses come with photochromatic lenses which are designed to meet the specific need of people who are looking for protection against stark sunlight. In photochromatic lenses users receive protection from dangerous UV rays as the glasses are coated with special chemical which makes them change to a dark tint when confronted with sunlight. Otherwise when there is no sunlight these remain unchanged and do not tint.
No doubt about the fact that photochromatic lenses can not be considered suitable for those who are looking for fashion but these can be highly suitable for all those who do not wish to carry a separate pair of prescription sunglass when going outdoor. An important aspect of photochromatic lenses is that these do not tint black when the person is driving the car as windshield prevents most of the UV light from reaching the lens – UV rays or Infrared rays need to confront to blacken the glasses.
